The fifty gastrointestinal polyps, which were removed endoscopically frorn 47 patients at the Seoul National Univeraity. Hospital from January, 1978 to September, 1983, were reviewed with regard to the clinical and pathological features. The observed data are as follows; 1) Fifty polyps were reoved from 10 patients with gastric polyps and 37 patients with colonic polyps. Out of 37 patients 26 were male and 21 female, the sex ratio being 1.2: 1. 2) The gastric polyps were located in the body and antrum and 90 per cent of the colonic polyps were found in the left colon, especially in the rectosigmoid colon. 3) Out of the 10 gastric ployps snared, 8 could be retrivevd, 2 being lost. The histological examination showed that 3 were hyperplastic polyps, 2 gastritis verrucosa, 1 inflammatory polyp and the remaining 1 revealed intramucosel carcinoma with borderline epithelium. 4) Fourty polypectomies were performed in 37 patients with colonic polyps. Histological examination revealed that 24(60%) were adenomatous polyps, 9(22.5%) retention polyp, 4 (10.0%) inflammatory polyp and 3(7. 5%) Peutz-Jegher's poIyps. Among the adenomatous polys, 4 cases were complicated with focal adenocarcinoma. 5) Except the 2 cases of post-polypectomy bleeding, no other complication was encountered. The one case of hemorrhage after gastric polypectomy was treated with transfusion of 2 pints of whole blood, and the other case after colonic polypectomy required exploratory laparotomy because of inability of bleeding control by electrocoagulation.

The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

OBJECTIVE: To verify the effect of Matrigel, a ECM complex from Engelbreth-Holm-Swarm(EHS) mouse sarcoma on the preimplantation development and apoptosis of mouse fertilized eggs. METHOD: Late Pronucleus stage eggs were cultured through the blastocyst stage in the presence of Matrigel (0.5%, v/v). Characteristics of apoptosis and cell number assessed by Hoecst staining and TUNEL labeling at the blastocyst stage, respectively. RESULTS: Morphological development, number of cells per embryo was significantly increased but rate and number of TUNEL positive nuclei of the embryo were decreased in the presence of Matrigel. CONCLUSION: This result suggested that at low concentration of Matrigel improves both viability and morphological development in the preimplantation mouse embryos.

Pseudolipomatosis of the colonic mucosa has been recognized as a lesion featured with aggregations of gaseous spaces in the lamina propria, but its pathogenesis remains still unclear. This paper describes 6 cases of pseudolipomatosis occurring in the mucosa of stomach and large intestine, and the possible factors involved in gastrointestinal endoscopic procedure to produce gaseous entrapment in the lamina propria were analysed. All cases received either gastroscopy or colonoscpy before endoscopic biopsy. Mucosal tissues from both stomach and recto-sigmoid colon revealed multiple aggregations of small air-spaces resembling fatty infiltration in the lamina propria. Rarely were similar infiltrations within the muscularis mucosae and adjacent lymphoid follicles. Evidence for pneumatosis cystoides intestinalis or ulcerative colonic lesion was not associated, although one showed a small gastric ulcer nearby. Repeated inflations and deflations of the stomach or colon during the endoscopic procedure with miner mechanical trauma by instrument to the mucosa seem to contribute to its pathogenesis.

The purpose of this paper is to review the colonofiberscopic findings in the 21 patients with tuberculous colitis, diagnosed by colonofiberscopic findings including histopathology and by follow-up observation after anti-tuberculosis chemotherapy. The results are as follows: 1) The male to female ratio was l. 33(R:4) and the average age of the patiets were 34. 9 years in men and women respectively. 2) The chief complaints were abdominal pain in 15 cases(71.4%), diarrhea in 14(66.7%), weight loss in 12(57. 1%), anorexia in 8(38, 1%), and so on. 3) Anemia and an increase in ESR were major abnormalities in hemogram. 4) On the chest X-ray examination, 65% of the cases showed active tuberculous lesions and the barium enema disclosed the changes suggesting tuberculous colitis in 52. 6% of the cases. 5) On colonofiberscopy 8 cases were ulcerative, 6 were hypertropbic and 7 were ulcerohypertrophic. 6) Histopathologic examination of the biopsy material from the colonofiberscopy revealed granulomata with caseation necrosis in 2 cases, granulomata without caseation necrosis in 8 cases, and the findings of chronic inflammation in 11 cases. 7) This study suggests importance of colonoscopic examination including histopathologic study of the biopsy material in the diagnosis of tuberculous colitis. The diagnostic efficieocy would be much improved if bacteriological examinations of the specimen could be developed.

A case of cystic lymphangioma of the mesentery with severe and persistent abdominal pain in a 22-year-old man is presented. The cyst was filled with chylous fluid. Microscopically, numerous nerve bundles were incorporated within the lymphangiomatous walls, and some protruded into the lumen. The above findings lead to a suggestion that mesenteric lymphangioma may differ from those in the other sites by its abundance of incorporation of nerve bundles into the lymphangiomatous walls, and that increase of tumor size by intracystic accumulation of chylous fluid may subsequently result in increase of intraluminal pressure to compress the nerve bundles with which abdominal pain is much enhanced.
